For an industrial activated sludge treatment process, the biomass concentration (X) is 2,200 mg VSS/L and the substrate concentration (S) is 50 mg BOD5/L. Using the following values, find the net microbial growth rate (rg'). Max substrate utilization rate (k) = 5 mg BOD5/mg VSS-d Half saturation constant (Ks) = 60 mg BOD5/L Microbial yield coefficient (Y) = 0.6 mg VSS/mg BOD5 Endogenous decay (death) rate constant (kd) = 0.06 /d

Question
For an industrial activated sludge treatment process, the biomass concentration (X) is 2,200 mg VSS/L and the substrate concentration (S) is 50 mg BOD5/L. Using the following values, find the net microbial growth rate (rg').
Max substrate utilization rate (k) = 5 mg BOD5/mg VSS-d
Half saturation constant (Ks) = 60 mg BOD5/L
Microbial yield coefficient (Y) = 0.6 mg VSS/mg BOD5
Endogenous decay (death) rate constant (kd) = 0.06 /d
